Thanks for laying out the details of your concern, @bamsing-gmail-co. I'd like to share an insight about changing the default country of your QuickBooks Online (QBO) account.
The product's country that you choose when signing up for the account becomes the default region. There isn't an integrated way that'll let you change the country of your subscription.
In the meantime, you may want to create a new account with the United States subscription, and then cancel your account with the Australia subscription to switch to another country.
- Go to this link: https://quickbooks.intuit.com/choose-country/.
- Select the North America section and choose the United States.
- Choose whether to subscribe now or use a 30-day free trial and the type of subscription you will be using.
- Click Add another company, then enter your existing Intuit login credentials.
- Follow the on-screen instructions to set up your account.
Here's an article you can read to learn more about how you can cancel your account: Cancel your QuickBooks Online subscription or trial.
In addition, you can import your customers, suppliers, chart of accounts, and products and services list from the old account to the new one. Please refer to this article for a detailed process: Move your lists to QuickBooks Online.
The Community and I are always around to help you with your concerns besides changing your default country in QBO. I'm happy to lend a helping hand. Have a good one!
